TencentOS Server 4: storm (TSSA-2024:1013)

medium Nessus Plugin ID 276126

Synopsis

The remote TencentOS Server 4 host is missing one or more security updates.

Description

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the TSSA-2024:1013 advisory.

 Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

 CVE-2023-43123:
 On unix-like systems, the temporary directory is shared between all user. As such, writing to this directory using APIs that do not explicitly set the file/directory permissions can lead to information disclosure. Of note, this does not impact modern MacOS Operating Systems.

 The method File.createTempFile on unix-like systems creates a file with predefined name (so easily identifiable) and by default will create this file with the permissions -rw-r--r--. Thus, if sensitive information is written to this file, other local users can read this information.

 File.createTempFile(String, String) will create a temporary file in the system temporary directory if the 'java.io.tmpdir' system property is not explicitly set.

 This affects the class https://github.com/apache/storm/blob/master/storm- core/src/jvm/org/apache/storm/utils/TopologySpoutLag.java#L99 and was introduced by https://issues.apache.org/jira/browse/STORM-3123

 In practice, this has a very limited impact as this class is used only ifui.disable.spout.lag.monitoring

 is set to false, but its value is true by default.
 Moreover, the temporary file gets deleted soon after its creation.

 The solution is to use Files.createTempFile https://docs.oracle.com/en/java/javase/11/docs/api/java.base /java/nio/file/Files.html#createTempFile(java.lang.String,java.lang.String,java.nio.file.attribute.FileAtt ribute...) instead.

 We recommend that all users upgrade to the latest version of Apache Storm.

Tenable has extracted the preceding description block directly from the Tencent Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
